Au naturel. The warmth of champagne diamonds and softly matte gold make this week’s stack really glow. Two Rebecca Overmann rings showcase the natural beauty of caramel-hued diamonds, one a tawny coffin-cut solitaire and the other a ravishing rose cut stone accented by upturned cognac baguette cuts, all set in Rebecca’s signature 14k matte finish gold. These modern marvels are set off by two vintage rings, showing the subtle beauty of old gold in an old euro cut solitare ring and the gorgeous natural patina of a well-worn silver in a Georgian era 5-diamond ring.
